I'm needing to change the T-belt but noticed a few part numbers for the kit (water pump, belt, etc) and wanted to know which one's you guys go with. 2006 wrx. Is it worth it for the more expensive blue belt?
Second, I noticed that when i get off the gas, my idles stays elevated, 1500 rpm, for about 5 to 10 seconds, then goes back to normal. Is this a problem or normal operation? I hand't noticed it before.
